Serial No. 508,714.

This invention relates to machines for operating upon shoes and is herein illustrated as embodied in a machine for pounding the bottoms and uppers of shoes. 5 An object of the invention is to provide an improved pounding machine in which work, such as a shoe, can be presented to pounding tools for operation upon the bottom or upper of the shoe in such a way that the operator will to a great extent be relieved from strain caused by rapid vibration of parts of the machine.

To this end, the illustrated embodiment of the invention consists in a machine comprising a frame, a pounding tool carried by the frame, and an arm pivotally mounted-upon the frame and extending above and outwardly from the tool. Preferably, and as shown, the outer end of the arm carriesa ack which is pivotally mounted on the arm and is movable axially of the arm for presenting clifferent portions of work carried by the jack to the pounding tool. The weight of the arm and of the jack carried by it tends to force work, such as a shoe, in position on the jack, toward the pounding tool with the re sult that the operator need only guide the shoe relatively to the tool in performing the pounding operation, thus eliminating the greater part of the strain to which the operator would otherwise be subjected. As shown, the machine is provided with a rotary pounding tool for operating upon the k bottoms of shoes and also an oscillatory tool for operating upon the uppers of the shoes. The mounting of the ack and arm provides for the presentation of different portions of a shoe to the tools in operating upon either the heel part or forepart of the bottom of the shoe or upon the upper. Preferably, inanually operable means is provided for moving the jack axially of the arm toward the oscillatory tool. This means, illustrated as a treadle and connections arranged to move the arm axially, absorbs much of the vibration resulting from operation of the tool. thus further relieving the operator from strain.

Other objects and features of the invention will be apparent from the following description when taken in connection with the accompanying drawing and will be pointed out in the claims.

In the drawing, the figure is a side elevation of a pounding machine illustrating one 5r 0 embodiment of the invention.

The illustrated pounding machine comprises a frame carrying a rotary shaft 12 which is operative to rotate a heating or pounding drum 14. Along the periphery of the drum 14 are carried a plurality of poundmg rings or tools 16 for operating upon the sole of a shoe presented substantially tangentially of the drum, The frame 10 also carries a shaft 18 for operating an oscillatory tool 20 used to pound the side portions of the upper of a lasted shoe. For a more de-- tailed description of the parts thus far described and their operation, reference may be had to United States Letters Patent No. 1,019,878, granted March 12, 1912 upon an application filed in the name of Orrell Ashton.

For presenting shoes to the pounding tools there is provided a work support or jack 22 which comprises a bar 2 1 having at one 7 end a split collar 26 within which is clamped; by bolt 27, a pin 28 having a reduced end portion 29 over which is forced a toe-post or stud 30. Pivotally mounted on the stud 30 is a pad 31 for engaging the forepart of a shoe, such as a lasted shoe 82, to be carried bythe jack. The other end of the bar 24 carries a slide 3 having a projection 35 upon which is frictionally held a heel-post or stud 36 for engaging the heel part of the lasted shoe. The stud 36 has a pin 38 adapted to enter the last pin hole 40 of the last. The slide 34 has a ratchet 42 for engaging a rack 44 on the bar 24; to lock the slide in any position of adjustment. In locating a shoe in the jack, the forepart of the shoe is pressed against the pad 31 and the slide is moved along the bar until the pin 38 can be inserted in the last. The slide is then moved toward the stud 30 until the pin 38 is cramped against the waits of the last pin hole, in which po-. sition the lasted shoe will be firmly held in the jack by the pressure exerted between the pin 38 and the pad 31, release of pressure being prevented by engagement of the ratchet 42 with the rack'44. The studs and 36 are interchangeable so that either the forepart or the heel part of a shoe, as desired, can be positioned axially of the pin 28. The construction above described provides means for firmly supporting shoes, the slide readily permitting adjustment of the pin 38 along the bar 24 for accommodating shoes of different sizes.

The jack 22 is carried by members which permit movement of the jack in presenting different portions of the shoe to the drum 14 or to the oscillatory tool 20. To this end, the rearward portion of the frame 10 is provided with an extension 46 at the upper end of which is carried a shaft 48. Loosely mounted on the shaft 48 for pivotal movement relatively to the frame extension 46 is a bracket 50. The bracket 50 is bifurcated, the bifurcations being in the form of collars 52 within which is slidably mounted an arm 54 extending outwardly above and across the drum 14 and the oscillatory tool 20. Upon the outer end of the arm 54 are two collars 56 which form part of a bracket 58 which is rotatable about the axis of the arm 54 but which is held against longitudinal movement along the arm by stop collars 60 and 62. The pin 28 of the jack 22 passes through the bracket 58 and is secured thereto by a lock collar 64, there being sufficient play between he collar 64 and the collar 26 to permit niovemcnt of the jack 22 relatively to the bracket 58 about the axis of the pin 28. Thus the jack can be oscillated about the shaft 48 in moving a shoe carried by the jack toward or away from the drum 14, can be rotated about the axis of the heel-post 30 on the pin 28, and can be swung about the axis of the arm 54 in presenting different portions of the bottom of the shoe transversely thereof to the drum. In addition to the movements above-mentioned, slidable mounting of the arm 54 in the collars 52 provides for movement of the jack axially of the arm 54 in directions tangentially of the periphery of the drum 14, thus making it possible to present different portions of the bottom of the shoe longitudinally thereof to the drum. The pivotal mounting of the jack for movement about the axis of the heel-post 30, in addition, provides means for locating different portions of the upper of the forepart of the shoe laterally in operative position relatively to the oscillatory tool 20.

The weight of the arm 54 and its asso-r ciated parts operates to force the work downwardly against the drum 14, there being a stop 66 upon frame extension 46 operative to engage a lug 68 upon the bracket 50 thus to limit downward movement of the latter when there is no work in the jack.

Manually operable mechanical means is provided for moving the jack in directions axially of the arm 54 or substantially tangentially of the drum 14 in presenting the bottom of a shoe thereto or in presenting the upper of the shoe to the oscillatory tool 20. To this end, the arm 54 has on its under surface a rack 70 in mesh with a sector 72 rigidly mounted on the shaft 48. Secured to the shaft 48 is a bell crank 74 one end of which is connected to a treadle rod 76 arranged to be operated by a treadle 78. Rotation of the sector 72 efiects movement of the arm 54 relatively to the bracket 50, thus to move the ack 22 tangentially of the drum 14 and to raise or to lower the jack relatively to the oscillatory tool 20. The arm 54 is prevented from sliding out of the bracket 50 by a lug 80 on the bell crank 74, which is adapted to engage the upper surface of the stop 66, thereby preventing rotation of the sector 72 beyond a point at which the arm 54 would leave the bracket 50.

In the operation of the machine, a lasted shoe, such as shoe 32, is positioned in the jack 22 in the manner above set forth. The operator grasps the shoe lightly and moves it across the surface of the drum 14 which effects a pounding action upon the bottom of the shoe to shape it to the last. The mounting of the jack for movement about the axis of the pin 28 and for movement about the axis of the arm 54, as well as movement axially of the arm, permits presentation of different portions of the bottom of the shoe to the drum without difficulty, the weight of the jack and arm being suflicient to absorb most of the vibration caused by the blows struck by the rings 16 of the drum. If required, the operator next performs a pounding operation upon the heel seat of the shoe, which is accomplished by rotating the jack upon the axis of the pin 28 until the heel part of the shoe occupies the position formerly held by the forepart of the shoe, the pounding taking place in substantially the same manner as before.

1 Vhen it is desired to operate upon the side 7 bracket 50, moving, the jack toward the os- 1 cillatory tool 20. The operator directs the forepart of the shoe toward the tool, a light pressure upon the treadle being sufficient to present the forepart of the shoe to the oscil- .r

latory tool which operates to smooth out the upper and to shape it to the last.
